To create transclusions between different texts, you need to select a section of text that will form a connection between the pages, based on a common subject:

Think of a category that is the common ground for the link. For example if two texts refer to a similar issue or specific concept (eg. 'rawdata'), formulate it without spaces or using underscores (eg. 'raw_data', not 'raw data' );

Edit the two or more pages which you want to link, adding {{RT|rawdata}}<section begin=rawdata /> before the text section, and <section end=rawdata /> at the end (take care of the closing '/>' );

All text sections in other wiki pages that are marked up through the same common ground, will be transcluded in the margin of the text.
